Question

Solve this system of equations using substitution. Put your answer in ordered pair form, (x, y).
5x + y = 1
3x + 2y = 2

Answer 1

5x + y = 1
3x + 2y = 2

for that you need to isolate y in first equation
y = -5x +1

then plug in that y to the second equation
3x + 2y = 2
3x + 2(-5x+1) = 2
3x+ -10x+2 = 4
3x - 10x +2 =4
-7x = 2
x = -2/7

Answer 2

then plug in -2/7 for x to get y
5x + y =1
5(-2/7) +y = 1
-10/7 +y =1
y = 17/7
